I still run a couple of SuSE systems, one for myself and one for a client. Today, after doing some non-kernel updates, I got the message There are some running programs that use files deleted by recent upgrade. You may wish to restart some of them. Run 'zypper ps' to list these programs. I tried this, and yes, it lists processes that need restarting so they will pick up the updated libraries etc. This feature is only available on SuSE 11.2. Does Debian provide anything similar? No doubt somebody will write a script to do it.
